My butternut squash leaves are turning yellow fast. I have checked the stems for fluid and it is not discolored or slimy. I cannot find any borers and this happened within a week period. I have tried to keep adequate water on them as well. The thing about it is, that it happened in less than a week. I used Miracle Grow garden soil and added bagged cow manure before planting. I have acorn squash next to them and Zucchini and they look OK. If you can suggest anything, please do. Thanks, Jacob Seitz ALSO, can I pull the squash which are not ripe yet and process them for freezing?

How often do you water them? Under or over-watering could cause yellowing of the leaves.
Squash roots spread out in the top 12 inches of soil and grow several inches per day, competition with other shallow-rooted vegetables can deprive leaves of the nitrogen they need to form chloroplasts -- the cells that keep them green. Since you have acorn squash and zucchini nearby, this could be a distinct possibility.
